MUSlC-BOX ATTACHMENT FOR CLCJCKS.

EPEC'IPICATION forming part of Letters Patent No. 347,047, dated August 10, 1886.

Application filed April 1, 1896.

To aZZ "whom it may concern:

Be it known that I, CHARLES H. JACOT, a resident ofHoboken, in the county of Hudson and State of New Jersey, have invented an Improvementin Clocks,of which the following is a full, clear, and exact description,reference being made to the accompanying drawings, in which Figure 1. is aface view, partly in section, of a clock containing my improvement. Figs. 2, 3, and i are face views of parts of the improvement, showing the same in various positions.

The object of this invention is, principally, to connect the 1n ainspring of a clock-work with a music-box attachment,l'or revolving the cylinder thereof, and with a lifting attachment on the mi unto-hand arbor for setting itin mo tion.

Clocks havehcretoforc been provided, in some instances, with music-box attachments; but in no case was such an attach ment capable of being wound through the dial of the clock or of being set in action by the mini'ite-arbor. 1f itis remembered that astrikin g-clock strikes at least twenty-four times during one day, it will be readily understood that a music-box attachment of the ordinary kind, adapted to make at most from six to ten rotations of the cylinder, is not applicable to a striking-clock. Many efforts have been made to contrive a means for adapting such an attachment to a strikingelock; but as far as known to me they have all. been unsuccessful, and, if apparently successful, were so at the expense of much room in the clock-case and of considerable skill in the handling thereof. By my invention every person who has been in the habit of winding striking-clocks will be able tokeep the improved clock in proper operative con dition.

In the drawings, theletter A represents the frame of the clock-work.

B is the minute-hand arbor or center post of the clock, which carries aprojecting toe, a, or other projection for setting the music-box attachment in operation.

0 is the winding-shaft for the mainspring D, that actuates the hands of the clock.

E is the winding-shaft of the mainspring F, that actuates the music-box attachment of the clock. The shaft E carries a toothed wheel,

which is driven by the niainspring F, and which, by a system of toothed wheels, (I, e, and f, gears into the cylinder G of the music-box attachment. This cylinder G is provided with projecting pins, in the usual manner, for actuating thekeys II. By a toothed wheel, 9, the cylinder G communicates motion to an arbor, 7/, that revolves the fly i. Normally aprong, j, on a lever, I, enters a hole or notch of the wheel 9, as in Fig. 1, so as to prevent the cylinder G from revolving. A spur, m projecting from the lever I, may also arrest the iiy '2', as shown in Fig. 1. The weighted end of the lever I has a pin, I, which bears on a disk, at, that is mounted upon the minutehand arbor B, being the same disk on or near which the projecting toe a is located. That end of the lever I which rests on the disk n is weighted, or under the influence of a spring, so as to keep the pin j in the wheel g, and prevent the cylinder (i from revolving. lVhenever the toe a comes in contact with thelcver I or any projection thereof to lift its weighted end, the other end of the love r will be lowered and the cylinder (1- liberated, whereupon the said cyl inder will be revolved by the action of the mainspring F.

Fig. 2 ofthc drawings shows theposition of the lever I at the time the toe u affects it.

I have also deviscdan attachment by means of which the cylinder G may be set in action or arrested without dependence upon the position of the too a. This attaehmentis in form of a slide, J, which is supported by the framework A, and which can be pulled to carry an arm, 0, under the weighted end ol'thelever I, as in Fig. 3, so as to lift the same and set the music going. The same slide J can be pushed inward, as in Fig. 1,into thepath of the fly i, to arrest the motion of the cylinder.

My invention is not limited to a clock having only two mainsprings. The same clock could have another mainspring for actuating the ordinary striking attachment, in which case I would so arrange theparts that the music would be sounded before the striking at allowance would have to be made for the varying periods of time that are consumed by the striking action.

1. In a clock, the winding-post E, adapted tachment was set in action, so that no special IOO to pass through the dial of the clock, in combination withits mainspringF and gear-wheels that are controlled by said inainspring, with the cylinder G of a music-box attachment, and 5 with the lever I, and with the minute-hand arbor B and toe a, for moving said lever I by said minute-hand arbor, as specified.

2. The minute hand arbor 13, provided with the disk at and toe a, in combination with the [0 weighted lever I and with the cylinder G of the music-box attachment, as and for the purpose set forth. v

3. The minute-hand arbor 13, having disk 02 and toe a, in combination with the lever I, cyllever I, fly t, and cylinder G, and with the toe a, which is moved by connection with the minute-hand arbor B of the clock, substantially as and for the purpose shown and described.
